M35.3 CONNECT THE MECHANISM
Compare Qwen3 dense and MoE models with reasoning modes
Add "/no_think" to a question and Qwen3 answers at once; leave it off and it reasons at length first, with the same weights. See how that switch was trained, and why the huge MoE caches less than the dense 32B.

Lesson overview
Add "/no_think" to a question and Qwen3 answers at once; leave it off and it reasons at length first, with the same weights. See how that switch was trained, and why the huge MoE caches less than the dense 32B.
What you’ll explore
- The original Qwen3 release connects dense and MoE architecture choices with staged pretraining, reasoning-oriented adaptation, mode fusion, and distillation; compare exact checkpoints and mode-specific inference budgets.
